New Revision: 26418
URL: http://svn.gna.org/viewcvs/relax?rev=26418&view=rev
Log:
Implemented the compile_1st_matrix_iso_cone_free_rotor() function.
This is for the lib.frame_order.iso_cone_free_rotor module. The function will
calculate the 1st
degree in-frame frame order matrix for the free rotor isotropic cone model.
